Operation of sensor
There are two micro switches in the housing of the
sensor. The spacer pin activates the switches in two
different positions.

ing status of the brake.

The sensor only shows the wear status reliably when the brake is activated (locked). If the brake is not activated
(unlocked), a statement about the condition of wear cannot be given.
The wear of the brake pad is only measured if the brake is activated. If the brake is not acti-
vated, there is no signal.
"Pre-wear" is indicated as soon as the brake pad has worn off so that the brake pads need
to be replaced.
!
The brake pad needs to be replaced immediately if the signal indicating the status „end
wear“ is displayed. Please note chapter 5.1 Replacement of brake pads.
Fail-safe operation
A proper operation is only ensured if the state/wear sensor is wired properly. This provides a signal since a switch
(NO) is locked which is normally unlocked.
